Interpreting a string in a stream dump

Question

I am trying to figure out this line in a stream dump

"RMI TCP Connection....." daemon prio=3 tid=0x0000000106f12000
   nid=0x1e10 runnable [0xfffffffe48dfe000]   

What is the address after launch? Looks like the stack address is the top of the stack?

Answer 1

In the source code, it is called last_Java_sp, so it is the top of the stack (or the last known top of the stack).

// print guess for valid stack memory region (assume 4K pages); helps lock debugging
st->print_cr("[" INTPTR_FORMAT "]", (intptr_t)last_Java_sp() & ~right_n_bits(12));
